Liverpool are believed to be keen on a summer move - provided they finish in the top four - while Barcelona are long-time admirers.

And according to the Daily Star, Spurs are drawing up contingency plans for if Vertonghen does depart, with French defender Mathieu top of their list.

Although primarily a left-back for much of his career, the 30-year-old has been a regular at centre-half for Valencia in the last two seasons, as well as a wealth of Champions League and Europa League experience.

The two-cap French international has reportedly been watched on a number of occasions this term by Spurs scouts, with them optimistic that a summer deal can be agreed.
